FIG. 1. The (A, B, C, D) soil properties, (E) root density distribution, and (F) initial condition of the simulations. (A) Distribution of scaling factors for the water characteristic function. (B) Distribution of scaling factors for the hydraulic conductivity function. (C) Distribution of the minimum contact angle; the mean contact angle is 5 ± 1.5°. (D) Distribution of the maximum contact angle; the mean contact angle is 90 ± 20°. (E) Distribution of the root density factor b. (F) Distribution of matric heads as an initial condition for the simulation; the averaged matric pressure head of the soil profile is 60 hPa.
